Look up “blockchain symbol,” “blockchain illustration” or “blockchain clipart” and you’ll get lots of different images, but nothing common or canonical. I mean, not like you’ll get for “laptop,” “hard drive” or “cloud.”
So the other day somebody drew the above on a whiteboard.
I like it, so I’m sharing it, in the public domain.
You’re welcome.
Perhaps a matryoshka doll?
Well, the idea is to have something a person can draw on a whiteboard or throw on a slide to represent a blockchain. Kind of like a vertical cylinder represents storage or a cloud represents a cloud.
